Troubleshooting
Hoya Australis 'Lisa' problems — and how to fix them
Hoya Australis 'Lisa' (Hoya australis 'Lisa') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Overwatering and root rot
Soggy soil causes yellowing leaves, mushy stems and root rot - the most common cause of death. Let the top 1-2 inches dry between waterings and use a fast-draining mix.
Mealybugs
The most frequent pest; appears as white, cottony clusters in leaf joints. Wipe off with isopropyl alcohol on a cotton swab or treat repeatedly with neem oil or insecticidal soap.
Reverting or fading variegation
Insufficient light pushes the cream and yellow markings back toward plain green; some leaf-to-leaf variation is normal. Move to brighter indirect light to maintain colour.
Not blooming
Young or low-light plants rarely flower. Give bright light, let it become slightly root-bound, feed in the growing season, and never cut off the bare flowering spurs (peduncles), which rebloom each year.
Droopy, wrinkled leaves
Limp, puckered foliage usually signals underwatering or, conversely, rot-damaged roots. Check soil moisture and root health before adjusting watering.
